2. the generation of rubidium marking information

Below exemplarily narrate the generation method that some typically add rubidium marking, but it will be understood by those skilled in the art that following description does not constitute restriction of the present invention.The configuration that adds tagged element in this technological process mainly is benchmark with the quality, design different tagged element prescriptions, utilize the standard solution of the tagged element that has prepared, it is joined in a certain amount of carrier, add needed additional affirmation composition again, thereby form a kind of chemical element mark.Put it briefly:

(1) selection contains the compound and the element ratio of needed tagged element;

(2) select carrier, mix mutually with carrier according to the compound of prescription with a certain amount of tagged element;

(3) material that contains the chemical element mark that mixes in (2) step is combined with the article of wanting mark, form the chemical element mark.

The compound of described tagged element comprises the inorganic salts and/or the organic salt of this tagged element.In same chemical element mark, preferably use of a sort salt.Described carrier comprises: organic solvent and/or inorganic solvent, solid state powder etc.

Selectively, can in described (2) step, add the additional composition of confirming.Described additional affirmation composition can be visible coating, visible ultraviolet pigment, test agent and/or micro mark etc.

In above-mentioned (3) step, can in the production run of article, add, can also combine with the article of wanting mark by the material that contains the chemical element mark that includes but not limited to smear, spray, deposit, soak, stir and/or mode such as printing will mix, carrier solvent volatilizees or solidifies, and tagged element wherein partly is attached to article surface, part is infiltrated article inside, forms the chemical element mark.

More particularly, can consider following technology:

Prepare the standard solution of tagged element.According to the prescription that designs, can utilize the method for preparing standard solution to prepare the certain density standard solution of various chemical element marks, the solvent of this solution is water normally.Utilize this standard solution to prepare the chemical element mark again.Be more convenient for like this operating.

Select carrier.Carrier is to be beneficial to the material that chemical element is combined with the material that is labeled.Carrier can be immiscible with the standard solution of the hydrate of above tagged element, and tagged element can separate with carrier solvent.During application, major requirement is to help the surface attachment of this tagged element in surface that is labeled article and infiltration article inside.As selection, the solvent-borne type carrier can be water or ethanol etc., makes homogeneous phase solution, and tagged element can fully or partly be penetrated in the article.When using, tagged element and carrier are mixed, and minimum on demand, be attached to article surface and infiltrate article inside.Tagged element can or use under the environment arbitrarily at arbitrary surfaces and arbitrary temp.The key effect of carrier is attached to the article surface long enough time, so that make the chemical element mark can be attached to article surface and infiltration article inside.A lot of article surfaces, as: wood, paper, rubber, or steel etc., process of osmosis can be finished rapidly.Finer and close material, as: plastic cement and evanohm etc., under the condition that cooperates unconventional carrier solvent, process of osmosis may need the long period.

Specifically, selectable bearer type preferably can be considered following a few class:

I, can form multiphase mixture with tagged element: this carrier solvent is that the organic carrier solvent can comprise aliphatic hydrocarbon, aromatic hydrocarbon or alcohols etc., (representative is oily molten lacquer, varnish and lacca).The operator is to select to be fit to another factor of carrier solution because of the safety problem that the occupation contact needs to consider.The solution of water and alcohol radical may be that the potential stimulus smell is minimum in view of this consideration.Various flowable varnish can air-set, without any need for catalyzer, can form cleaning, hard surface after the drying, can combine closely with a lot of surfaces, and the solvent of such lacquer is aromatic hydrocarbon normally, as: toluene.Preferred carrier solvent of the present invention: varnish.Can be used for article such as metal, plastics.

II, form homogeneous mixture with tagged element: the water-solubility carrier solvent can be an ethanol, ethylene glycol and other water-soluble surface-active composition that accounts for the most of number percent of component.Can form very soft homogeneous phase marking composition, carrier solvent becomes dry rapidly, and tagged element is retained on the article, and such carrier solvent can also be used for plastic article.

III, epikote: this resin is to mix mutually with another kind of catalyzer in use, solidifies afterwards, but also has a great deal of owing to hardening loss can't be used before using.This epikote has very strong perviousness, and good acid resistance and antilysis are arranged, and when using this carrier solvent, mark can form visible.

In order further to strengthen the effect of chemical element mark, for example under the situation that the article ad-hoc location is marked, for ease of the location, can also in described chemical element marking composition, add existing affirmation composition, as auxiliary composition, it is generally comprised within all chemical element marking compositions, and it can be exempted by requirement of client.Below be some additional non-limitative examples of confirming composition:

I, visible coating: use fluorescent paint coating to form visible chemical element marking composition.Coating mixes according to client's demand, but preferably mixes the chromatogram that many coating forms a kind of uniqueness.Such as: use 25% volume ratio compo, and coating is dissolved up to coating fully with also mechanical concussion in the powder-form adding carrier solvent.This mixing has formed the basis with the marking additives method for making of quality form metering.

II, visible ultraviolet pigment: it is the powerful ultraviolet pigment of a kind of performance, and measures than form with quality, needs the accurate measurement of safeguarding.For example, use 1 to 200

W/W calculates.Dyestuff adds in the liquid-carrier with powder type and machinery concussion dissolving.These pigment can satisfy the almost demand of any specific identification.

III, test agent: check is met highly basic and is shown aubergine with Powdered phenolphthalein test agent.Certainly, also available blue thymolphthalein (thymolphthalein) indicator.Mix and the machinery concussion.Also can use other acid base indicator.

IV, micro mark: can add the micro marks of default coding, also can add the micro marks of client's special requirement.Be not mixed into carrier solvent, but be kept in the suspending liquid.Because gravity, when carrier liquid was static, they can sedimentation.Consumption is for for example restraining micro marks with 1 in per 25 gram liquid.

In addition, mark combines with article, by the information of comprehensive judge mark and/or the information of article itself, determines the comprehensive information accurately of this tagged items.For example, article can comprise bar code (visible stickup or the be printed on the article outside surface) identification marking of dominance simultaneously, comprise recessive rubidium marking feature (element is hidden in the material inside of article, thereby invisible, is recessive) simultaneously.When detecting, two kinds of features need be met simultaneously and identification could be passed through, counterfeit article can only be forged the dominant marker, but can not forge hidden indicium.

According to an aspect of the present invention, above-mentioned technological process of the present invention can be configured to the robotization assigning process.As previously mentioned, stored in the Database Systems at a large amount of prescriptions under various materials and the condition, the selection of prescription can take to generate automatically and be recorded in the robotization mode of database.
